well on iPhone 5 I installed lock info to see if it works, the lock info scrolls fine and to get the miWeather to scroll I have to start scrolling in the area of the screen above lockinfo (where the time and city are displayed). Sorry I don't have 4 or 4s to test on-

it would be better I guess if the lock info would scroll with the miWeather rather than the miWeather scrolling behind the lockinfo, but it's probably just too much stuff scrolling

I don't guess I ever did really on the lockscreen- I was always more interrested in whatever widget I had going than lockinfo- or whatever else i was working on in the lockscreen- i got really into that rotating cube when it was first being developed -I just slid to unlock then just open whatever app and do it - or use notification center when apple finally put that into ios
